TESLON Expanded PTFE Tape


TESLON Expanded PTFE sealant tape is a spooled Joint Sealant Tape made of 100% virgin PTFE material with micro-fibrillated internal structure for excellent stability. TESLON PTFE is resistant to all chemical products and solvents with the exception of alkaline materials. It has good resistance to elevated pressures and has a high thermal stability. TESLON expanded PTFE tape is odourless and tasteless making it suitable for food application. Upon compression, it forms a thin, hard ribbon that fills in surface irregularities and creates an extremely tight seal. It is capable of withstanding a wider range of pressures, temperatures and chemical environments than any other soft gasket.

TESLON Expanded PTFE joint sealant ensures an effective, enduring, and cost-effective seal, making a valuable contribution towards keeping your production and manufacturing processes optimised.
